The Baker parents (Martin and Hunt) and their 12 children go on holiday to a lakeside resort, where they soon find themselves competing against Jim Murtaugh (Levy), his trophy wife (Carmen Electra) and their eight over-achievers.
Someone, somewhere, seems to think that the concept of a really, really big family is inherently hilarious – and in that they're completely mistaken, as this unnecessary sequel shows.
Steve Martin and Eugene Levy dial it back as the competing pater familias, both with improbably beautiful wives who spend their time swishing their perfectly blow-dried locks and rolling their eyes. Amid unfunny slapstick routines and utterly predictable scrapes, few of the 20 kids get a namecheck, let alone a role.
There are a few moments of family bonding and bickering that do resonate, and a largely against-type turn from Carmen Electra as, like, the insightful one, but they're rare nuggets in a script that always places schmaltz over substance.
The quality cast just about manages to pull this above one-star ignominy, but a couple of good chuckles can't redeem this sappy mess.
